Application iled'eiitember e, 1912. Serial No. 718,571.v

To all wfzomz'f mag/.concern Be it known that we, JOHN lll. FARLEY,lvlATrLnA S. Finnair, and DAVID l?. FARLEY, citizens of the UnitedStates, residing at Cleveland in the county of Cuyahoga and .State ofGino, have invented certain new and useful improvements inCeiling-Sleeves for Fluid-Pipes, of which the following is aspecicatien.

This invention relates to ceiling sleeves for iiuid pipes, such assteam, hot water, hot air and other pipes placed in buildings forcirculatipg fluids, all substantially as shown described andparticularly pointed out in the claims. Y

ln the accompanying drawings, Figure l is a vertical sectional.elevation of our new and improved sleeve members lin working relation, asection or" a pipe and a cellular asbestos or like covering for the pipeinclosed by the said sleeve members. Fig. 2 is a side elevation, reducedof the several parts shown in ll ig. i. Fig. 3 is a perspective view ofthe upper of said sleeve members, and Fig., llis a perspective view ofthe lower Vof'said members, the same being in section or in two lgetlier as one.

The invention as thus shown comprises two sleeves, A and B,respectively, and means for fastening said sleeve together and adaptedto be used in insulating pipes, tubes and the like Where they passthrough ceilings or lioors in buildings, and while we 'carts adapted tobe bound topreferably show and employ a cellular asbestos coveringconsisting of sections C and C for the pipe l) it should be understoodthat any preferred style or kind of nonconducting covering can be used'.However, a cellular asbestos covering as shown herein is deemed thebest, and in the practical use or application of the sleeves it iscustomaryl to place the covering on the pipe and ,the sleeve A about thecovering before the ceiling or floor is laid and then to build up to thesleeve. In such case the serratedor toothed top flange 2 rests upon thelicor and the section C comes on the inside and rests on flange 3 of thesleeve. '.lliefsaid sleeve A is split lengthwise and has a tongue e atone of its vertical edges adapted' to engage slot 5 at the other of itsver tical edges and 'provide for diderences in size of covering, andflange 3 below is radially slitted or divided to spread the samehorizontally, and thus the sleeve ii is made an inclosing andvsupporting part :tor the packing or covering which passes Talenten apr..ao, isis.,

through the floor and serves as a protection thereto against heat in thepipe P. The saidv sleeve A also has a bead 6 about its lower portionwhich both affords strength and becomes 'a medium of support Jfor whatwe term the grab sleeve B suspended from or upon said bead. Thus itoccurs that the upper covering part Gis supported or carried by theflange 3 and is placed in position as the building is being erected andthe said sleeve A also becomes a means of support for the sleeve Bengaged thereon as shown.

The sleeve B is supplementary tosleeve A and serves to eieot a jointedconnection of the pipe cover therein. To"this end the sleeve B is made atwo-part or two-section member adapted to be engaged about theA upper ormeeting end of the Alower'section C and also about the upper sleeve A.Thus the sleeve B has an upper inner annular groove 7 of a size to tcomfortably upon the bead 6, and an annularbead about its lower portionserving as a'support -tor the clamping band b, and also has serrationsor teeth 9 extending inward at its lower edge adapted to bite or grabinto the sect-ion C and help to hold it up in a sustained and closedcontact against the end of the upper 'section C. The said sleeve B ismade in two separate parts or halves because they are of sheet yinetaland,v being beaded, cannot be bent to open as would be required if theywere made in a single piece. As it is the said parte or halves are cutto size to inatch at their `edges'when itted closely upon theA sleeve Aand their teeth 9 are adaptedto tongue 10 vand theother a slot l2through which said tongue engages and can be bent back into lockingyposition. 'Finally a suitable sheet metal band o or its equivalent,'

vengage in section C, and one part has a say a tie wire or wires',"isplaced about the body of sleeve B between its beads endg, l clamped orotherwise tightly lined thereon. f

By the foregoing construction no portion of the covering can leave theceiling to show dirt nor break the ceiling by expansion or contractionofthe supporting parts. The band l) is preferably lacquered' if it be ofa strip of thin sheet metal and is shown as having a Wire loop 13 in itsend adapted to, be engaged by the tongue 14 but, as already stated: asuitable binding of wire maybe ier y used for this purpose. A Coveringof Canvas, not shown, may be drawn over all the exposed portion ofthejoint to improve the appearances. lt is customary to put on one piece ofcloth Where risers are exposed from lcop to bottoni in the rooms. Nooeiling'plates are required With this structure and there is no dangerof tearing` the ceiling while doing the work, as oeeurs when oeil- ,ngplates used and which are liable to tear the ceiling when the pipesexpand un` der a high heat.

That We olann is:

l. A pipe and an asbestosI covering tube about the same in a hole ina-iloor and an asbestos extension tube next beneath said covering tubeabout said pipe7 in combination with a split sleeve about said tubehaving an outwardly turned flange about its top at the top of said holeand an inwardly turned flange at its bottoni on Whiolrsaid covering tuberests and vprovided with a bead about its lower portion and means at itsmeet-ing; edges to lock said edges together, and a grabbing sleevehaving an annular groove engaged over said bead and bestos extensiontube.

2. A. pipe and an asbestos covering tube about the same in a. hole in afloor, a split sleeve in said hole about said tube having an outwardlyextending projection about its top and` inwardly extending projectionsat its bottom engaged beneath the lower end of said tube, in Combinationwith tWo part sleeve suspended upon the lower portion of saidsplitsleeve and having` inwardly ex tending pointed teeth at itsl loweredge, an extension asbestos tube abutting said eovering` tube andpenetrated and held by said teeth and a band about said two-part sleeveclamping the saine on said split sleeve and about said extension tube.

ln testimony whereof We atlix our signatures in presence of twowitnesses.
